Justice minister Knut Storberget hailed the "fantastic" work on Tuesday done by Norway's police after meeting senior officers in the wake of last week's twin attacks in which 76 people were killed.

"I had the opportunity to thank police in Oslo and other districts and other organs for their fantastic work," Storberget told journalists.

"These are people who worked much harder than you could expect of anyone, these are people who interrupted their holidays and who volunteered to help from all parts of the country."

Aside from showing a willingness to come to the nation's aid, the minister hailed the efforts of the "men and women of the police" to re-establish "security" and "normality" after the attacks.

The Norwegian police have come in for criticism from the local media over the time it took them to reach the Utoeya island on Friday and apprehend self-confessed mass killer Anders Behring Breivik after a shooting spree there that claimed 68 lives.
